On May 2nd, the monument will raise entrance fees by $3 to $10 per car. The pedestrian and cyclist entrance fee will be $5, a $1 increase.

It’s the first fee increase in six years at the monument.

The annual park pass, which provides unlimited entry for one year, will go up from $20 to $25. Limited supplies of the $20 annual passes have already been printed, so those will sell at the old rate until they sell out, even if bought after May 2nd.

Officials say revenue from entrance fees is used to replace exhibits and update infrastructure.

The monument will offer 16 fee-free days this year. The next ones will come the week of April 16.
